POST PARCEL, BAG, SACIQAND AN ALOGOUS SEALING DEVIGE.

Application filed April 30, 1923. Serial No. 635,637.

To all who-m it may concern.

Be it known that I, WILLIAM BARBER SMITH, a subject of the King of Great Britain, residing at South VVa-nstead, Essex, England, have invented certain new and useful Improvements in and Relating to Post Parcel, Bag, Sack, and Analogous Sealing Devices, of which the following is a specification.

The present invention relates to improvements in and relating to post parcel, bag, sack, and analogous sealing devices particularly applicable for the strings or cords or the like of parcels or the like or analogous purposes.

According to the present invention in a sealing device consisting of a metal plate or disc which may be marginally stiffened, having a depending rim; also depending marginal prongs, or tangs, or teeth, adapted to be pressed through several folds or layers of material and turned over by an appropriate driver or clincher or press preferably so formed as to cause the prong points to fold b-ackwardly and re-enter the material, the depending rim is serrated between the prongs for gripping the string, cord, or the like, when the prongs are clinched through the object, particularly through the end folds of the wrapper of a wrapped and tied up parcel. v

Conveniently and advantageously the driver or clincher anvil is formed so as to clinch the prongs inwards or against that local part of the object which is under the head of the fastener, the object thus being gripped between the head and the folded over prongs.

For the purpose of accommodating strings, cords, or the like of difierent thickness, the prongs are unequally spaced round the head to provide more space between the prongs in one direction than another, as for example in the case of a four pronged sealing device with a rectangular prong setting more space is thus provided in one direction between the prongs than in the direction at right angles to the first direction.

The mouth of the barrel in which the sealing device is placed head first preparatory to driving it by a plunger is provided with diametrical notches for the two fold purpose of passing over the string or the like and forming a positioning mark for the sealing device so that this shall be correctly placed in the barrel to allow the string or the like to pass between the prongs.

The anvil of the driver or clincher may comprise a shallow circular concave gutter or groove at the free end of an arm adapted to be placed under the object to be sealed.

The plungers of the drivers or clinchers may be actuated in any appropriate manner such as directly by the pressure of the hand or indirectly through a lever, screw, cam, or other mechanical efiicienoy device.

The invention is illustratedin the accompanying drawings, in which Fig. 1 shows a blank suited for a string tied post parcel, bag, sack, or like seal.

Fig. 2 an elevation of the blank, Fig. 1, shaped ready for use.

Fig. 8 a side View of a hand lever actuated driver or clincher too-l for use with the seal shown in Fig. 2.

For sealing objects such as the end folds of post parcels, bags, sacks, or the like, or for analogous purposes, a pronged fastener is bent from a blank of sheet metal as shewn in Fig. 1 into the form represented by Fig. 2 serves well.

As shewn this fastener consists of four marginal prongs Z so unequally spaced as to give more space for string or the like in one direction than the other. The head of the fastener is stifi'ened by a marginal head m and has a serrated depending rim a between the prongs Z for gripping the string or the like.

Such V a fastener is may be driven or clinched by a driver or clincher tool, Fig. 3, consisting of a staple-like frame 0 having a flattened lower extremity 39 provided with an inwardly turning clinching groove, the

other and upper extremity being provided with a sliding barrel 1), with diametrical notches g at its mouth, and lever operated plunger 1* for driving the fastener 70 placed in the barrel 7). The notches 9 receive the string and serve as a positioning mark for correctly placing the fastener 70 in the barrel 10 so as to allow the string, cord, or the like to pass between the prongs.

After driving the plunger 7' recedes under the influence of a spring and thereafter the barrel rises, the retraction of the barrel facilitating introduction of the anvil under the object.

What I claim is A sealing device comprising a substantial- March 18, 1924. 1,487,673 I D. SOPER WASHING MACHINE Filed Dec. 23, 1922 him I lNVENTOR
